Hi everybody, thank you for reading my profile. Let me share a few things about myself. I was born in the Dominican Republic and moved to Wisconsin over 25 years ago. I really enjoy the 4 seasons that Wisconsin has to offer. I enjoy sports, especially football, and I'm a big fan of all the sports teams in Wisconsin.

Prior to getting into the auto business, I was a stay at home mom and a substitute teacher for 12+ years in West Bend, WI. 3 years ago, I came to Heiser Chevrolet Cadillac to look for a car for my daughter. The car that I came for on Friday, was sold on Saturday... (I went home to think about it).... It prompted me to say, "if cars sell this fast I'm in the wrong business", (just kidding of course, I loved my teaching job)... After numerous calls from management and my sales reprehensive Samantha, I joined the Heiser team! I love it! I pride myself on integrity, not being high pressure, you tell me what you need and want and I will make sure you find what you are looking for... I know you will not only be completely satisfied with me, but my whole Heiser team. I'm looking forward to working with you and welcoming you to our Heiser family!

Lies after lies. They'll say anything to get you in the door and then the trickery begins. And their sales manager is a complete and pompous jerk! I'll never buy anything from any Heiser dealership ever again! Neither will anyone I know as I have made my opinion very loud and clear to everyone I know! This dealership should be ashamed

Had an exceptional car buying experience with Maria

Had an exceptional car buying experience with Maria Fuller. Maria has a good personality and was a pleasure to work with. This was our first car to have all the "bells and whistles" and she took the time to explain everything to us why we sat in the car. Maria told us that if we had any further questions, to feel free to stop by and she would be happy to help, which we feel is going above and beyond. We have had our Equinox for a week now and love the car and are happy we came to Heiser. Ryan G. made the financing part of it fast and painless and answered any questions we had. Looking forward to having the car serviced at Heiser and would definitely recommend Heiser!

Very dissatisfied.

Very dissatisfied. Took it in for a noise coming from the front. They looked it over and told me my wheel bearing was bad which I thought was it. But then they said I had severe corrosive on my oil cooler lines. They should have caught that a while ago if it was that bad. They look over the underside when they do an oil change.. Very disappointed.

Had my car towed in for a second time due to transmission issues. The first time they had it for two week. I got it back for approx 2 weeks then it failed the second time. When it was towed in they had it for 4 weeks before they found out what was wrong. Then 2 more weeks for parts to be delivered. I thought it was TERRIBLE hiw long it took them to Diagnose and fix the issue.
